It’s like this: you get a slightly-scary physical symptom and you go and tell your doctor and she frowns and says “well, we better run some tests and make a date with a specialist”, and you go to the specialist and he works you over and looks at the tests and says “yeah, that’s a weird one, it happens sometimes, we don’t know why, it might happen again, it won’t hurt you, don’t worry about it.”
